My speedometer AKA the Rover Slowdometer, which is there to remind the series driver of how slow they are going is making a tremendous noise. WIth out any intervention at all, yet, it will occasionally make a loud noise and the needle will act more irratically than usual. I might assume that A, the cable is not fully engaged in the back,, or the gear mechanism is shot and they are not engaging, or some other type of Rover ghost is in effect. Ill figure it out, but wondering on and taking suggestions. Cheers.
